Fix: Windows 10 Store Error 0x8007064a

Quite a few Windows 10 users have, since the Operating System’s launch, reported a problem where all of their attempts to install specific applications from the Windows Store end with the application being downloaded but the installation of the application failing. When the installation fails, users affected by this issue see a generic error message containing error code 0x8007064a informing them that there was an error during installation. While this problem has been observed to be considerably rampant among Windows 10 users, it has also been known to affect computers running on Windows 8 and Windows 8.1. In addition, this problem can also occur when trying to update applications via the Windows Store.

Users affected by this problem have confirmed that, in almost all cases, restarting the affected computer and uninstalling/disabling any and all firewalls and third-party security applications on the affected computer does not help. In actuality, this problem is most commonly caused by an issue with the Windows Store itself or messed up ownership of a specific registry key.

As far as Windows issues that render users incapable of installing applications from the Windows Store go, this is one of the more obscure and undocumented ones, which is why affected users often have trouble locating possible resolutions to this issue. Thankfully, though, the following are some of the most effective solutions that you can use to try and fix this problem:

Solution 1: Reset the Windows Store

If an issue with your computer’s Windows Store is the culprit behind this problem, resetting the Windows Store may just be able to fix the problem. To reset the Windows Store, you need to:

  1. Press the Windows Logo key + R to open a Run
  2. Type wsreset.exe into the Run dialog and press Enter.
  3. Wait for the resulting Command Prompt to reset the Windows Store. The Windows Store will have been reset when the Command Prompt closes itself.
  4. Restart your computer, and when it boots up, check to see whether or not the problem persists.

Solution 2: Perform a System Restore

All currently supported versions of the Windows Operating System have the magical ability to create system restore points every few days so that if something goes wrong, you can simply perform a System Restore and your computer will be reset to exact way it was when the restore point you used was created.

Performing a System Restore to a point in time before this issue existed on your computer is a pretty effective way of getting rid of it, although you are going to need a system restore point on your computer that was created before the your computer fell prey to this issue. If you do not know how to perform a System Restore on a Windows 10 computer, simply use the Restoring the System using System Restore Point section of this guide.

Solution 3: Make sure the ownership of a specific registry key is set to SYSTEM

If none of the solutions listed and described above worked for you, you may be in this bind because the ownership of a registry key named Packages within your computer’s registry is not set to SYSTEM. If that is the case, all you need to do in order to fix this problem is:

  1. Press the Windows Logo key + R to open a Run
  2. Type regedit into the Run dialog and press Enter.
  3. In the left pane of the Registry Editor, navigate to the following directory:

HKEY_CURRENT_USER > Software > Classes > Local Settings > Software > Microsoft > Windows > CurrentVersion > AppModel > Repository

  1. In the left pane of the Registry Editor, right-click on the registry key titled Packages (under Repository), and click on Permissions… in the context menu.
  2. Click on Advanced.
  3. Click on Change (located next to the name of the registry key’s owner).
  4. Type SYSTEM into the large open area labeled Enter the object name to select, and click on OK.
  5. Click on OK in the Advanced Security Settings
  6. Click on OK in the Permissions dialog, close the Registry Editor and restart your computer.

When the computer boots up, you should be able to successfully download and install applications from the Windows Store without ever running into any error messages containing error code 0x8007064a.
